Sometimes you need to get information abot some user. To do so you need the SiteUserInfoList. This list contains data about all user that visited the SharePoint site. This is how you can read the list with C# and CSOM: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 // build the SharePoint connection ClientContext clientContext = new ClientContext( "http://your site/" ); Web web = clientContext.Web; // get the userinfolist List siteUserInfoList = web.SiteUserInfoList; // build a query CamlQuery query = new CamlQuery(); query.ViewXml = "" ; // get the data IEnumerable<ListItem> itemColl = clientContext.LoadQuery(siteUserInfoList.GetItems(query)); clientContext.ExecuteQuery(); // work with the userinformations foreach ( var item in itemColl) { Console.WriteLine( "ID:{0} Email:{1} Title:{2}" , item.Id, item[ "EMail" ], item[ "Title" ]); }

In a previous post  I wrote an app to read and write data from the Host-SharePoint. To do this I made use of the SP.RequestExecutor. This class is used to get the permissions for reading and writing data into the Host-SharePoint. But there is a way to skip the authentification and using the URL directly. This makes your code much more beautiful and easy to read. All you need to do is to call a function (_spPageContextInfo.siteAbsoluteUrl). That function returns an URL and makes it possible to communicate with the SharePoint per JSOM and REST.  I also tried to call the URL with the function and make a context with another URL and this does not work. Even the Host-URL does not work. Another disgusting point is that the URL, which is returned by the function, is that it not contains the URL of the app and not of the host. It is a 'hybrid' that begins like the app URL, but ends earlier. 1 2 3 4 var url = _spPageContextInfo.siteAbsoluteUrl; context = new SP.ClientContext(ur

In some cases the "Edit Page" button is not visible too make sure no one makes some unallowed changes. This is a nice security hack, but what if you need to edit the page? There is an easy way to open the page in edit mode and that is the URL. Add one of the following extensions to your URL, right after the '.aspx'. To change the public view of the page add this: ?PageView=Shared&ToolPaneView=2 example: http://sp/Pages/default.aspx ?PageView=Shared&ToolPaneView=2 To change a personal view of the page add this (only if it is enabled): ?PageView=Personal&ToolPaneView=2 example: http://sp/Pages/default.aspx ?PageView=Personal&ToolPaneView=2
